Chaotic interface, incomplete adaptation for older synths like MKS-80, must use front panel on older synths To get half ass results. Need to use front panel and reconfigure the midi set up just to make it work half ass with TX-802. Didn't even bother with other synths after it crashed my DAW system and destroyed midi drivers. Tried on 3 different PC's with different cards. This thing sucks big time. Lousy uninformed tech support after waiting for 45 minutes.

If you want something that works right out of box with older synths then, get the unisyn but they don't update And haven't for years.

Good Points
Do give you more adaptations for latest synths. Bad Points
everything else.
